Cultivated blueberries (bot. Vaccinium corymbosum) can reach a height of a good three meters. If you choose one of the tall varieties, the question arises as to whether it can be grown on a trellis like the raspberry.
Do blueberries need a trellis?
growing blueberries on atrellisisnot necessary. The cultivated blueberry grows as a bush. The height of growth varies depending on the variety. However, for optimal development, the berry bushes need slightly acidic garden soil.
How do I plant blueberries in the garden?
Thesoil is crucial for blueberries in the bed. The shrubs prefer slightly acidic garden soil, which corresponds to a pH of 4.0 to 5.0. You can create optimal conditions by
- Dig a planting hole (60 cm deep, 100 cm wide)
- cover the ground with a layer of rhododendron or ericaceous soil
- insert the berry bush
- fill the planting hole with the special soil
- water the blueberries well with lime-free water
Tip
If you line the side of the planting hole with foil, you will prevent calcareous discharge from reaching the berry bush.
How do I grow blueberries in a pot?
For growing blueberries in containers, you should choose a large andheavy pot. Fill this about a third with brushwood and bark mulch. Usemoorbed or rhododendron soil as a substrate Since the blueberry does not tolerate lime, you should only water the shrub with rainwater.
Does the blueberry need pruning without a trellis?
Since blueberries grow slowly,young specimens do not need pruning Older bushes should be cut every three to four years to keep the berry bush in shape. Prioritize removing old shoots that bear little fruit. Leave two to three-year-old shoots as they produce the highest yield.
Tip
Mix blueberry varieties
Cultivated blueberries are self-pollinating, but produce more yield if they are cross-pollinated. It is therefore advisable to plant different types of blueberries. You can also extend the harvest time if you plant varieties with different ripening times in the bed.
